Clinical Outcomes After Implantation of Polyurethane-Covered Cobalt-Chromium Stents: Insights from the Papyrus-Spain Registry

The main indication of covered stents (CS) is coronary artery perforation (CAP), but, they have been increasingly used in other scenarios. Data on the long-term follow-up of CS is limited, and no studies have been conducted specifically using new-generation polyurethane-covered cobalt-chromium Papyrus CS. Purpose: to evaluate the clinical outcomes after hospital discharge of Papyrus CS and to compare their outcome after implantation in CAP or coronary artery aneurysms (CAA). We evaluated the baseline clinical characteristics, lesion subsets, procedural features and the outcomes after initial discharge of Papyrus CS implanted in 17 high-PCI-volume centers. 127 Papyrus CS were implanted in 108 patients (68 ± 1 years; 82.8% male) admitted for stable coronary disease (32.3%), NSTEMI (42.4%) or STEMI (25.3%). The number of CS per patient was 1.2 ± 0.6 (diameter: 3.5 ± 1.7 mm; length: 18.5 ± 3.7 mm). Angiographic success rate was 96%. CS diameter was larger in CAA (CAP:3.04 ± 0.5 mm vs CAA:4.1 ± 2.7 mm; p = .022). Intracoronary imaging techniques were used more frequently in CAA (p
